“Edge” is a slang term with multiple meanings in online culture, often related to the concept of delaying gratification or being on the verge of something. In some contexts, it refers to intentionally prolonging a state of excitement or anticipation without reaching a climax. Within “brainrot” discussions, it can also be used as a meme term to describe content that is intentionally frustrating or designed to keep viewers hooked without a clear resolution, contributing to a sense of cognitive overstimulation.
